Swift Springs Expands 7" Barrel Spring Lineup with New 475 and 525 Rates

Swift Springs is proud to announce the addition of 475 lb/in and 525 lb/in spring rates to its popular 7-inch Barrel Spring lineup. Developed in response to requests from competitors in the Whelen Modified and SMART Modified Tour series, these new spring options continue Swift Springs' commitment to delivering race-proven suspension solutions driven by customer feedback.

With availability in time for the 2026 racing season, racers now have even greater flexibility when dialing in their suspension setups.

Designed for Faster Suspension Response

Like the rest of the 7-inch Barrel Spring lineup, the new 475 and 525 rate springs feature a reduced coil count. Fewer active coils help decrease the spring's open speed, allowing the suspension to react more efficiently during changing track conditions.

This design provides teams with another valuable tuning advantage by improving the overall responsiveness of the suspension without sacrificing consistency.

Improve Compliance by Reducing Shock Rebound

One of the primary benefits of the 7-inch Barrel Spring design is the ability to reduce rebound damping in the shock absorber. With less rebound required to control the spring, the suspension can move more freely over bumps and changing track surfaces.

The result is increased compliance, helping the tires maintain better contact with the racing surface while providing drivers with a more predictable and controlled feel throughout the race.

Racer-Driven Development

The addition of the 475 and 525 rates is another example of Swift Springs' collaborative approach to product development. After receiving requests from teams competing in the Whelen Modified and SMART Modified Tour series, Swift engineered these new rates to give racers additional setup options for varying track conditions and chassis combinations.

By listening to racers and responding with purpose-built products, Swift Springs continues to expand one of the industry's most comprehensive racing spring lineups.

Available Now for the 2026 Racing Season

The new 475 lb/in and 525 lb/in 7-inch Barrel Springs are in stock and available now through authorized Swift Springs dealers. Whether you're preparing for opening day or refining your suspension package throughout the season, these new spring rates offer another proven option to help maximize chassis performance.

As always, Swift Springs remains dedicated to providing innovative, high-quality suspension components designed by racers, for racers.
